Title: Improvements in feed mechanism of combing machines
IPC: D01G19/10
Filed: 1922-02-27
Abstract: 188,611. Nasmith, J. W. Feb. 27, 1922. Combing-machines. - The feed device is arranged to draw back a short length of the previously fed material within the nipper as it commences to recede from the detaching-rollers and before it closes. A secondary feed nipper inside the main nipper, or a feed roller which can be rotated in either direction is employed. When a secondary nipper is employed the adjustment of the main nipper relative to the detaching-roller is arranged to adjust also the secondary nipper relative to the lip of the main nipper. In a combing-machine as described in Specification 132,987 the nipper frame N<2>, which swings about the pivot N, carries levers L pivoted on studs 16. The levers L are connected to arms 31 carrying the lower jaw F of the secondary nipper; the arms 31 having bowls 30 mounted on them engaging ledges 35 on the nipper cheeks. The levers are also connected by links 34 to blocks 36 swivelling in projections 11 on the levers 9 secured to the shaft 10. The lever L being anchored by the link 34 oscillation of the nipper N<2> causes a relative movement of the jaw F within the nipper. The upper jaw F<1> of the secondary nipper is carried by arms 37 pivoted at 38 on the arms 31. These arms are operated to open and close the jaws F, F' by means of a shaft T<3>. A link 40 carrying a pin 40<a> is connected to an arm 42 on the shaft. A spiing 44 surrounds the pin to give the necessary spring pressure to grip the material. A cam M on the comb-cylinder shaft operates, through a rod 46, the shaft T<3>. By regulating the connection between the link 34 and the arm 11 on the shaft 10 adjustment is obtained of the position of the jaws F, F<1> relative to the main nipper. Adjustment of the main nipper relative to the detaching-roller D is obtained by means of the shaft 10 as explained in the above-mentioned Specification. Movement of this shaft also gives the necessary relative adjustment of the jaws F, F<1> within the main nipper. A feed roller may be employed carrying a pinion which is engaged by a toothed sector, to give a forward and then a reverse rotation as the main nipper swings towards and from the detaching-roller. The sector is attached to the link 40 and operated by the means described above for moving the upper jaw F<1>.

Abstract: 745,919. Dividing-engines. NATIONAL RESEAHCH DEVELOPMENT CORPORATION. June 8, 1954 [March 6, 1953], No. 6332/53. Class 97 (3). In apparatus for dividing a linear scale a continuously rotating screw 11 moves a nut 23, 24 of the kind described in Specifications 684,846 or 708,539, [both in Group XXIX], endwise movement of the screw is prevented by means of a bearing 13 of similar construction to the nut, the journal running in the bearing having a series of parallel circumferential grooves 17, and the nut is used to produce relative movement between a photographic plate 28 or the like and a projecting system 29 which projects an image of a fine slit 32 on to the plate, this system being momentarily illuminated at regular intervals determined by the rotation of the screw. In apparatus for effecting an angular adjustment, an arm carried by the member to be adjusted is engaged by a peg or the like on a nut coacting with a screw, the peg projecting transversely to the screw axis and the nut being of the kind described in Specifications 684,846 or 708,539, [both in Group XXIV]. As shown, the screw 11 is supported in bearings 12, 13 with strips 14 of cork or similar resilient material engaging the journals in three regions. The journal in bearing 13 has a large number of shallow parallel grooves inscribed thereon, e.g. in the manner described in Specification 717,678, [Group XIV], while the journal in bearing 12 may be similarly grooved, or smooth as shown. Driving means 18 rotates the screw 11 evenly and continuously through a fork 19 engaging a cross-pin 21. A fine helix 22 is inscribed on the greater part of the length of screw 11 and is engaged by a nut with hinged jaws 23, 24 provided with cork or like strips 25 and urged together by springs 26. The upper jaw 23.carries a frame 27 for the photographic plate 28, the frame 27 engaging a fixed roller 31 which prevents the nut from rotating. A xenon flash tube 33, when triggered, illuminates a slit 32, an image of which is formed on plate 28 by a lens system 29. A cam on the driving mechanism 18 closes a switch to trigger tube 33 accurately at the same phase of each revolution of the screw 11, so that a scale of equallyspaced lines is formed on plate 28. If desired, a second switch in series with the first may be operated by a second cam driven at a slower speed so as to close the switch just before each of a periodic series of closures of the first switch, so that the line interval is a multiple of the basic interval. Part of the slit 32 may be covered by a shutter 34 operated periodically by an electromagnet 35 so that some of the lines are prolonged. Apparatus wherein the nut engages an arm rotating a turntable carrying a circular plate is also described. The total angular movement is small and may be restricted by limit switches. The angular position of the plate on the table may be adjusted.

Title: Improvements in or relating to the testing of coal for the determination of ash content and to the processing of coal
IPC: G01N23/08
Filed: 1954-03-05
Abstract: 750,650. Determining ash content of coal by radiation. STAMICARBON N.V. March 5, 1954 [March 7, 1953], No. 6558/54. Drawings to Specification. Class 40 (3). [Also in Group XXXV] In a method of determining the ash content of coal the ray absorption-capacity of the coal for Roentgen radiation of wavelength greater than 1.74 Š and less than 4.5 Š is determined. At these wavelengths the absorption of such inpurities as iron does not differ materially from that of the other ash forming substances. The required radiation may be generated in a tube provided with a cobalt anode and beryllium window, operated at a voltage of 14 kv. and provided with a quartz monochrometer. The sample under test consisted of 57 mgs. of soot ground to a mean particle size of .3 mm. and filled into a cylindrical cuvette of 7 mm. diameter and having a bottom window of beryllium. The intensity of the transmitted radiation was measured with the aid of Geiger counters. If measurements are made on a continuous stream of coal the fluctuation in ash content may be used to control coal cleaning operations by continuous measurement, by change in absorption capacity between samples or by comparison of successive samples with a standard.

Filed: 1945-03-15
Abstract: 591,965. Valve super - regenerative circuits. FERRANTI, Ltd., WOOD, H., WILLIAMS, F. C., and WHITEHEAD, J. R. March 15, 1945, No. 6604. [Class 40 (v)] To maintain a super-regenerative receiver at constant sensitivity, noise voltages, other than those occurring at the quench frequency, are utilized to provide a controlling voltage for varying the regeneration. The super-regenerative valve 1, quenched by valve 7, feeds signals to the diode 15, the rectified signals being fed over choke 18 to an audio amplifier 19 and an amplifier 23. By employing a circuit 25, 26 in the cathode lead, tuned to the quench frequency, noise components at or near this frequency receive little amplification. The output from valve 23 is rectified by, diode 30 to give a negative potential, which is applied to the grid of valve 36, the cathode being connected over resistance 43 to the grid of valve 1. A decrease in sensitivity causes the D.C. potential from diode 30 to fall, reducing the negative bias on the grid of valve 36 so that the cathode potential rises, increasing the potential on the grid of valve 1. In a modification, Fig. 2 (not shown), the diode 30 is inverted and the varying cathode potential of valve 36 is applied to the cathode of valve 1. In a further modification, Fig. 3 (not shown), valve 36 is arranged to operate with an anode load, the anode being connected to the inductance of tuned circuit 6. In a further modification, Fig. 4 (not shown), a pentode is employed as the super-regenerative valve 1, the output voltage from diode 30 controlling the potential of the suppressor grid. Alternatively, using the arrangement of Fig. 3 (not shown), the screen grid may be connected to the anode of valve 36. Specification 585,353 is referred to.
